TROLLEY.

Specification of Letters Patent.

Patented Get. 28, 1913'.

AppIication filed April 8, 1913. Serial No. 759,672.

To all whom it may concern Be 1t known that T, SEoIsMUNDo GARCIA VALLEs,a citizen of the Republic of Cuba.

and a resident of Habana, in the Province of Habana, Cuba, have inventeda new and Improved Trolley, of which the following is a full, clear, andexact description.

- This invention is an improvement in trolleys, and has reference moreparticularly to a trolley having loosely mounted brushes.

The object of this invention is to provide an inexpensive, simple andreliable trolley in which the working parts can be quickly interchangedwithout the displacement of the trolley.

The invention consists of the construction and combination of parts tobe more fully described hereinafter and fully set forth in the claim.

Reference is to be had to the accompanying drawings forming a part ofthis specification, in which like characters indicate correspondingparts in all the views and in which:

Figure 1 is a side elevation of an embodiment of my invention; Fig. 2 isan elevated central section of same; Fig. 3 is a section on line 33,Fig. 1; and Fig. 4: is a perspective view of the brush. 7

In the appended drawings, 5 represents the bifurcated end of thetrolley. Between the sides 6 forming the bifurcation a trolley wheel 7is positioned. The trolley wheel 7 is provided with a bushing 8 intowhich fits an axle 9, the ends of the same bearing in the sides 6 of thebifurcated end of the pole. Mounted on the axle and adjacent the wheelare washers 10, and positioned between the washers and the inner facesof the sides 6 on the axle 9 are brushes 11. The brushes 11 extenddownwardly alongside the inner faces of the sides 6; and the lowercontacting end 12 of same is bent to follow the sides of the pyramidalrecess 13 formed at the base of the bifurcation. The pyramidal recess 13is formed by the sides forming the bifurcation and also by twotransverse wall portions 14 extending transversely of the sides 6forming the bifurcation and integral with same and lying slightly belonthe edge of the wheel 7. 14 adjacent the sides 6 are pins 15 contacting"with the ends 12 of the brushes 11 and normally forcing these endsagainst the sides of the pyramidal recess 13 formed by the side walls 6.The space between the pins '15 and the adjacent side is such that aneffort is required to place the end 12 of the brush into said space.

To prevent the displacement of the axle 9 from the sides 6, the axle andthe sides are provided with registering apertures into which cotter pins16 are fitted. WVith my device, when the brushes 11 are worn out,

as the case is in general, same can be quickly replaced by firstdisengaging the cotter pins,

extracting the axle, removing the wheel with the washers, and thensimply pulling out the brushes, forcing new brushes into place andreplacing the removed parts. From this it can be seen that there is nonecessity for removal of'the trolley tov the shops for the interchangingor riveting of parts as is done at present.

Having thus described my invention, what Engaging the two walls.

I claim as new and desire to secure by Letters Patent is: y

In a trolley, a pole having a pyramidal recess in its end, and armsextending beyond said end; a wheel between said arms; an axle supportingsaid Wheel; brushes at eachv side of said wheel on said axle adjacentthe arms and each having a portion extending into said pyramidal recess;and

pins in said recess forcing said brush portions in said recess againstthe sides forming the bifurcation.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

, SEGISMUNDO GARCIA VALLES.
